Pendent 'tassels' appearing like inflorescences, though not of raspbery character. ? galls, but I can find none like them.
No identification made yet.
No interactions present.
This looks like an example of phyllody, where the usual floral parts have developed as leaf like structures, often this is caused by an infections with a phytoplasma or a virus.
I think that you must be right, Steve, although this seems to be a very spectacular example. There are some pictures of the phenomenon here, but none as extreme as this.

Thanks, that sounds sensible (if hard to prove!)
I see now that the plant has at least one fruit that shows it to be Rubus fruticosus (i.e. Blackberry,not Raspberry), but that is a detail.
If possible, I will acquire a specimen to investigate further.
... but the foliage and stem armature is that of a raspberry. So before I noticed that some bramble foliage could be seen in the photograph, I was wondering about the possibility of a hybrid, but in the light of the presence of the bramble foliage I presume that the fruit belongs to that, and not to the raspberry.
My initial impression WAS Raspberry. I am sure your comment is correct: there is some Bramble showing amongst what is mainly Raspberry, and it is the latter that bears the unusual growths.
